To all whom it may concern: 1

Be it known that I, EMIL L. CLAUs, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Visconsin, have invented certain new and useful Improvements in Ignition-Torches for Gas-Burners; and I do hereby declarethat the following is a full, I

clear, and exact description thereof. My invention relates to new and useful lmprovements in devices adapted for association with a gas stove to light any one opening of any burner valve, or by reason of delay in ignition, as when the ignition is under independent manual control, a further object with respect to this automatic action being to simplify the operative steps in.-

cidental to use of the stove and to procure a prompt lighting action without necessitating the use of'both hands of the operato in procuring such prompt action.

A further and important object resides in the provision of an arrangement whereby, when the gas supply valve of the burner is open, an igniting torch of flame is projected only toward the burner which is opened in contradistinction to eizisting types of ignition devices, wherein actuation of the device effects the projection of torch flames to all of the burners, which it may at any time be desired to light, this arrangement in existing structures lessening the gas pressure and consequent force and efficiency of the torch which supplies the burner to be lighted.

A further object resides in the provision .of an igniter torch head adapted to selectively project igniting jets of gas toward any one of a plurality of burners to be lighted, and wherein means is afforded in a most economical manner for maintaining a pilot light to ignitewhichever torch jet is actuated.

ture which is eflicient and positive and which may be manufactured and associated with a conventional gas stove in a most economical manner.

With the above and other objects and advantages in view, WhlCll will be apparent as the description proceeds, my invention resides in the novel features of construction,

combination and arrangement of parts as hereinafter more particularly described and defined by the appended claims.

In the accompanying drawings:

Fig. 9 is a diagrammatic view showing a modified arrangement of the torch structure.

Fig. 10 is a detailed view of the preferred valve construction.

Referring now more particularly to the accompanying drawings, 10 designates the top of a conventional gas stove, including in the present instance four burners 11, from which the usual pipes 12 extend to the front of the stove, terminating in air mixing heads 13 into which extend the rear ends of the burner supply valves 14, the forward ends of said valves being threaded in the supply pipe 15 extending along the front of the stove. The usual valve. member 16 is mounted in the casing 14, it being provided with a transverse passageway 17 valve casing to permit the supply flow of gas-to the burner. [To providefor a torch supply of gas to the torch head upon actuation of any one of the valve members 16,

each valve member is provided with a well 18 communicating with the passageway 17 I and having a'port 19 extending therefrom 1 the spring 167' which retains the valve inemher in snugly seated position, thewell being slightly shouldered at the upper end of .itsscrew receiving portion whereby to seat a adapted to registeriwithan outlet port/v disposed below the plane'of the passageway 17, this outlet port 20 terminating in ,a nipple to which is secured a tube 21 extending to thetorch head. ,As shown in the detaile Fig. 10, the .well 18 may extend through the bottom portion of the valve memberand constitute at its lower portion the recess for receiving the usual "screw 16". for holding packing disk 18', preferablyiormed of lead or other soft metal to insure sealing of the lower portion'of the well-uponinsertion of the spring in assembling the. valve The.

entire valve structure may thus be readily.

and economically constructed. By, disposing the torch suppl port in a plane olfset from the plane of t e main passageway 17,

the desired normal size of the valve member may be maintained, it'being noted that the diameter ofthe valve member and the size of the main'supply passageway must be so relatively proportioned as to provide for a desired wide range of swingin movement of the handle of the valve mem er to effect the open and intermediate position of the valve, .avoiding a too sudden openingand closing action. i

In the embodiment of my invention shown in Fig. 1, the torch head is disposed centrally of the group of burners 11, and com; prises a block or body member 22 having a series of sockets 23 in one'side adapted to receive the couplings of the gas supply tubes 21 of the individual burner valves, the sockets being four in number in accordance with the number of burners illustrated. The inner sockets 23 communicate directly with vertical passageways 24, while the outer sockets communicate with convergent passageways 25 terminating at a second pair of vertical passageways 24, the vertical passageways being thus disposed in quadrangular relation. Torch tips 26 are secured in the upper 'ends of the passageways, each torch tip being provided with a jet aperture 27 adapted to direct the torch diagonally of the series of tips and between a pair of opposite tips toward a respective burner.

of whichever to'rcliis actuated; f is i screw 32.

most economically eifected by providing one" The hood for protecting the torch tipsand shielding the pilot light from currents of air: whici might extinguish it comprises a cylindrical body 28 bf such diameter as to receive and snugl fit the upper portions of bosses on the ho y member through which the torch passageways 24, extend, whereby the hood is thus detachably supported. The

torch ports of, the hood' are'iormed by drawing portions of the body wall'outwar'dly'in' tubular shape as shown'at 29 in Fig. 4, the

projections thus formed serving to deflect currents of air andtodra'in oflt' fluid which might be spilled from receptacles .on the stove and run down they wall of the h od.;-v

- Theupper portion of the hood wall is"cor -1 rugated to form series of vertical'channels in its outer periphery,-and a'closur'e cap 30 seats over the corrugated portion a of thewall, being provided with projectionsadjacent its to preventing closure 'of the upper ends 0 the passageways of thecor rugations. fMeans is thus provided for venting the upper portion of the hood to avoid ases therein"- the accumulation of dead which'might extinguish the pilot. The en- I tire structure may be most readil cleansed by removing the cap and eflicient rainage is afforded which prevents lodgment of matter in the passageways, it being incidentallynoted that while the corrugation passageways are shown and described as being formed in the body wall of the hood, they may as well be formed in'the wall of the cap 30. It is further noted that any air currents which enter the hood through the vent passageways-of the corrugations will be deflected upwardly against the cap arid thus broken in force to prevent the possibility of extinguishing the pilot light.

An exceedingly simple, efficient and readily manufactured torch head structure.

is thus-provided, which, while particularly adapted for use in connection with the general igniter device herein described may also be used in connection with other general types of igniters wherein a plurality of jets are to be discharged either singly or simultaneously toward a plurality of burners.

7 Taking up now the general operation of my improved device, and referring particularly to Fig. 5, it is noted that the valve member 16 of each burner unit is adapted for partial rotation through an arc of slightly more than-90, rotation through 90? procuring a fully open position of the valve from a fully shut-ofi' position, the torch ports 19 and 20 being at all times out of registry. open position will thenprocure registry of the torch supply ports, thus procuring the pr jection of a single torch jet toward the resiliective burner, andinasmuch as but a single jet is actuated, a maximum force of projection is rocured to insure lighting the burner. he valve member is then turned back slightly to initial full open position, thus extinguishing the torch.

An exceedingly simple structure and operation is thus afforded' for automatically lighting any one of the burners of a stove upon swinging movement of the valve of the respective burner to open position, it being noted that in the majority of instances it would not be desired to utilize the maximum flow of gas, and a slight return movement of the valve member would anyhow be ef-' fected to procure the desired intermediate position of the valve member for normal cooking operations.

Figs. 6, 7' and 8 show a modified structure wherein means is provided for procuring the torch action at the out-set of opening movement of the valve, thus still further decreasing the danger incidental to accidental open- I ing of the valve and consequent escape of unignited gas into the room. In this structure, the burner Valve member l6 disposed in the usual valve casing 14:, and provided.

with a main transverse passage ll, has a pair of diametrically opposed torch supply ports 19 disposed below the passage 17 and communicating with the well 18 "'of the valve member. The torch supply ports 19? of the'valve member are so disposed with respect to the torch port 20 of the casing that one of said lports 19 is adapted to register with the port 20* prior to full registry of the main supply passage 17 with the main ports of the casing when the valve member is rot'alted inclockwise direction. In the present structure, the'valve memberis adapted for continuous rotation in this direction, being provided with a series of, radial handle projections 33. Rotation of the valve member in the opposite direction to open the valve is prevented by a pivoted pawl 34 pivoted to and dependmg from an attachment member 35 which has its upper end'bifurcated to embrace the usual forward. depending flange 36 of the stove top 10, the attachment member being adjustably sethrough one of its furcations. This pawl is limited in its downwardly swinging 'movement by a stop 39 011 the attachment member and is thus held in'the path of the handle projections 33 of the valve memher and in an inclined position, being freely yieldable to permit movement of the handle projections therepast in a clockwise direction of rotation, but preventing movement A slight rotation'past the full -of the handle projections therepast in a counter clockwise direction of rotation. Thus, assuming that the valve is closed, a partial rotation of the valve member will procure registry of the torch supply ports as thevalve begins to open, thus lighting the burner. Movement to full open position is then effected, andthe intermediate and subsequent closed position of the valve is procured by a second quarter rotation in the same direction. Thus, whenever the valve is even partially opened, ignition of the burner is assured, counter clockwise movement of the valve member to open position being prevented in the present instance by the pawl 34, although it will be appreciated that any equivalent means may be employed. I

In some instances it is not expedient to dispose the torch head-at the center of the group of burners, for instance when as shown in Fig. 9 a central burner 11 is rovided. In such instances, a pair of torch leads A. are provided at the sides of the stove, each torch head being adapted to supply certain of the burners and being connected by the individual supply tubes 21 with the conventionally shown valves which control the respective burners. In this arrangement, two of the valves of the stove would. naturally be provided with pilot bypasses, one for each of the torch heads. In like manner, the oven burners of the stove may be supplied with automatic lighting means. The specific layout for the oven burners is obvious in view of the foregoing disclosure, and hence not specifically illustrated.

= While I have shown and described a preferredembodiment of my invention, it will be appreciated that various changes and modifications of structure may be employed to meet differing conditions of manufacture and use without departing in any manner from the spirit of my invention. It will be furtherappreciated that various phases of my invention may be used independently of the complete structure described,the torch head structure, for instance, comprising a simple and ellicient unitwhich may be used in connection with any supply means for the jets thereof. v I
